Sometimes I have other attributes I need to store on a Student instance, though. Can you use **kwargs and setattr to add attributes for any other key/value pairs I want to send to the instance when I create it?

first_class.py 
class Student:
    name = "Your Name"

    def __init__(self, name, sneaky=True, **kwargs):
        self.name = name
        self.**kwargs = "sowmya"

    def praise(self):
        return "You inspire me, {}".format(self.name)

    def reassurance(self):
        return "Chin up, {}. You'll get it next time!".format(self.name)

    def feedback(self, grade):
        if grade > 50:
            return self.praise()
        return self.reassurance()

    def __init__(self, name, **kwargs):
        self.name=name
        for key, value in kwargs.items():
            setattr(self, key, value)

kwargs stands for keyword arguments and acts like a dictionary. Note below for some inspiration if you may optionally set parameters in your init method. 

import random

class Dice(object):

  def __init__(self, *args, **kwargs):
    self.name = kwargs.get('name', 'no_name')
    self.sides = [1,2,3,4,5,6]

  def roll(self):
    return random.choice(self.sides)


d = Dice(name='first_dice')

print(d.roll())
